Roller encoder
RP-7400シリーズ
RoHS and CE compliant. Speed measurement: 120 P/R, 1200 P/R. Length measurement: 200 P/R.
Excellent ease of use, measurement is possible simply by contacting the roller. Uses a hard urethane rubber coated roller to prevent slippage. For speed measurement, the 1200 P/R model, when used in combination with the TM-4100 series, displays the speed directly, eliminating the need for complex calculations. Measurement is possible from 0.01 m/min. For length measurement, the 200 P/R model, when used in combination with the TM-4300 series, can measure in 1 mm/pulse increments.

* Roller encoders (for length measurement) may accumulate errors in measurement values due to installation conditions, roller slippage, roller wear, etc.
* The TM-4300 series reversible counter has a correction function, which can compensate for outer circumference errors caused by roller wear, etc.
*When measuring travel speed (m/min) using the RP-7400 1200 P/R and FV-1500 combination, please set the display unit to "USER".
